1. Altism. The CCP forces players to create alts. I don't talk here about off-grid boosting alt or tengu dual-boxing to run 10/10, but rather the fact that CCP does not allow to train more than 1 char. Why the heck I can't train 1 mission runner 1 pirate and 1 indy toon at the same time? That way I would be able to explore different careers and play depending on my mood the char I want. But no! CCP wants additional 15$ for every new char. Under no circumstances would I pay more than 15$/month. So that restriction simply annoyed me.

2. SP training. As I learned at some point there were no T2 items and so training worked as intended. So, the vet that spent 24 days to get level V would be only 2% more effective than someone who trained that skill till IV spending only 4 days. It allowed 'catching' up (not true but effective) with older players. However with introduction of T2 items/ships level V for very many skills became essential. Want armor tanking? Make sure you get hull upgrades til V. What T2 medium guns? Spend 20+ days to get them. Furthermore, to compensate CCP introduced faction modules (a bit better or equal to t2 items {i don't mean ammo here}). They are much more expensive than t2 but require less sp to use. I always saw it as a way to milk newer players (to sell plex) who are forced to equip them to be as effective as their higher sp counter-partners.

3. No secrets. When I started playing the first time I loaded the map I thought that there are remote regions where noone went yet and I can spend days looking for hidden treasures. How wrong I was. All space is colonized (even wormholes). Everything is known. Even how many ships can pass through this or that wormhole before it collapses and what enemies will spawn in this or that sleeper site.

4. Corps/recruitment. Since to be effective one needs t2 fits most corporations have solid 15-20 mil sp requirement. That number is not arbitrary. It simply reflects the amount of sp needed to fly T2 fitted T1/T2 frigates, T1/T2 cruisers, T3 battlecruisers and maybe battleships. And the process of recruitment is quite humiliating. "Make sure you fill our forms and don't forget to let us about yourself as well. If we like you, we will let you know within 2 weeks and schedule an inverview with you via teamspeak." Or some crap like that. Thank god, they don't ask for urine analysis. I feel some people take this game too seriously.
